The first record of morphologically abnormal wild fishes, Epinephelus coioides (Hamilton, 1822) and Cynoglossus cynoglossus (Hamilton, 1822), in the Parangipettai and Nallavadu landing centres along the south-east coast of India were reported. The caudal region of both of the fishes was completely deformed and fused. These abnormalities have been considered as an important indicator of environmentally induced stress to the wild fishes.
